For a particle undergoing free-fall acceleration, the acceleration vs. time graph is

A force F acts in the x - direction, its magnitude given by F = ax^2, where x is in meters and a = 5.0N/m^2 . Find the work done by this force as it acts on a particle moving from x = 0 to x = 6.0 m.

Two teams are pulling on a tug-of-war rope. The rope is NOT moving. Is this an example of a balanced force or an unbalanced force?
